1 Data 1.1 U.S. Refineries 1.1.1 Sources of data I match and compile three data sets on characteristics and imports of U.S. refineries collected by the U.S. Energy Information Administration (EIA): (i) capacity of distillation unit and upgrading units (parts 6-7 of form EIA-820: annual refinery report); (ii) imports of crude oil, (form EIA-814: monthly imports report) (iii) domestic purchases o...

The Evaluation of eCRM implementation in most of organizations will witness an increase in efficiency, staff satisfaction, and eventually customer satisfaction. The objective of this paper is to apply and compare the analytic hierarchy process (AHP), Fuzzy AHP and Fuzzy Topsis methods to evaluate the Parsian banks’ readiness in ECRM implementation. Primary data have been collected by means of q...

the purpose of this study is to evaluate the impact of self-fulfilling prophecy on the motivation and performance of national iranian gas company staffs. in this study, considering the importance of peoples’ perception and its role in motivation and consequently their performance in organization, we have tried to investigate the influence of one of these perceptual factors by using the correlat...

Reduction of greenhouse gas (GHG) emissions for mitigating climate changes is globally necessary. As a major GHG emitter, refinery sector responsible 14.1% China’s CO 2 emission in 2019. The flue associated with petroleum refining has high content, presenting potentials methanol and electricity co-production when the methane hydrogen dry are considered. To unlock green opportunity refineries, t...

investment in oil and gas upstream activities is very important for the exploration and development of oil and gas fields. different and various laws and regulations deal with the investment in upstream operations. by reviewing these various laws and regulations, this research paper tries to discuss to what extent these laws and regulations have created legal confident for foreign investment up...

We introduce Refinery, an open source platform for exploring large text document collections with topic models. Refinery is a standalone web application driven by a graphical interface, so it is usable by those without machine learning or programming expertise. Users can interactively organize articles by topic and also refine this organization with phrase-level analysis. Under the hood, we tra...

surge and rotating stall phenomena are two dynamic instabilities that occur in both axial and centrifugal compressors. surge is the stream instability phenomenon in compressor that imposes severe damages to the compressors. nowadays, suppressing surge phenomenon is one of the most important issues in oil and gas industries, especially when flow reduction or gas reflux is considered. this resear...

Wireless sensors and measurement devices are widely deployed in oil and gas refineries to monitor the health of the pipes. These sensors are deployed along the pipes in an open area and thus are subject to large scale failures due to cyber-physical attacks and hazardous environments. In this paper, we study the resilience issues in collecting data from a dense and large scale set of sensors dep...
